Septic Systems in New Hampshire

Most of New Hampshire relies on individual septic systems — and the state takes them seriously. Any structure connected to a water supply must have an NHDES-approved wastewater disposal system. Here are the key numbers:

Key Setback Distances

From	To	Min Distance
Septic system	Drinking water well	75 ft
Septic system	Wetlands	75 ft
Primary structure	Shoreline	50 ft
Accessory building	Shoreline	20 ft

What It Costs

Conventional System

$10k – $20k

Engineered / Alternative

Waterfront Inspection Law (RSA 485-A:39) — Updated Sept 2024

Buying waterfront property? If any part of the septic system is within 250 ft of the water, the buyer must hire a licensed evaluator for a full system evaluation before closing. If the system is failing, it must be replaced within 180 days. Sellers who are notified of a failure must fix it even if the sale falls through.
